Abstract

Generally, earth canals in paddy fields in developing countries collapse due to erosion and flooding under strong rainfall. Consequently, farming is often hindered. For sustainable maintenance and management, it is important that the irrigation facilities are made of technologies that can be implemented by the farmer themselves and with available materials. The wooden canal protection is a construction method, which satisfies this requirement. This paper aims to evaluate the durability of the wooden canal protection for local implementation at Ghana. By the visual inspection of the experimental plot, the main deterioration factor of the wooden canal protection has been termites, and the service life has been estimated to be about 12 months at the hill side in main canal susceptible to termites and about 28 months at the swamp side in main canal and in the branch canal which are hardly affected by the termites.
